vPile-VVires of Looms, of Which the following is a specification.'

My invention relates to the lubricating of the Wires used-in forming the loop or pile of carpets andthe like made on Jacquard and other like looms; and my invention has for its object to facilitate and improve the lubrication of the said wiresas they are pulled out of the loops or pile of the carpet preparatory to being again introduced between the y'arn and warpV for the purpose of forming other loops, a process well known .in this class of carpet-loom.

In order that my invention may be the better understood, I remark th-at it is usual to lubrieate the wires, before mentioned, by hand by the use of cylindrical or 'roller brushes containing oil-that is, liquid lubricant-which oil frequently causes the pile of the carpet to become greasy and with carpets having a light ground gives the top a more or less soiled and discolored appearance. Grreat` waste of 'oil also results from this the ordinary method 0f lubricating the pile-wires.

The object of my invention is to effect a. uniform and eliicient lubrication of each pilewire in such a Way that the objections hereinbefore referred to in the use of the ordinary hand method of lubrication are obviated.-

`In carrying my invention intoeffeot I em-, ploy a solid lubricant and automatically apply the same to the under sides or edges 0i the pile-wires,or preferably to both the underand upper sides 0r edges, in the ways hereinafter described, and illustratedin the accompanying drawings.

I will describe my invention in connection with means for lubricating both sides or edges of the pile-Wires.

For the lubricating of the upper edges of the pile-wires I employ a hard Wax-such, for example, as paraffin-wax or composite candlewax; but for the lubricating of the under Serial No. 126,146. (No model.) ,i 'i

edges or sides 0f the said pile-*wires I prefer t0 employ a softer wax, such a's is obtained by the mixing with paralin-waxjwhenin a melted state of sperm-oil in about-theproportion of seven parts, by weight, of paraffin-wax to twoxparts, by weight, of sperm-oil; The solid lubricants described are made into the form of cylinders somewhat resembling-in appearanceordinary wax candles. 4 Figure l of the accompanying drawings represents in front elevation a portion of one side of a Jacquard loom, showing the ordinary mechanism by which the'pile-Wires are drawn out of Lhearpet and also'the new or improved means for lubricating the' said Wires constituting my inventiongand Fig. 2 is a plan of the same. Fig. 3 represents, partly in elevation and partly in section, fthe lubrieating appliance detached, drawn to a larger Figli is a sectional scale than Figs. l and 2. view at right angles to Fig; 3. Fig. 5 represents, partly in plan and partly infhorizontal section, the mechanism by which fthe lower solid lubricant is rotated, as is hereinafter explained; and Fig. 6 represents in plan the mechanism by which the upper solid lubricant is rotated, as is also hereinafter explained. Fig. 7 is a cross-section on the line a: w, Fig. `3.

drawings. v

a is the lower solid lubricant, made, preferably, of the specially-prepared softened lwax`,'hereinbefore describedgby which the .lowerL orr under sides of the pile-,wires c are lubricated, and b is the cylinder of harder wax, by which the upper sides.- of the pilewires are lubricated. The lubricating-cylinder b is inserted in a tubularholder e, carried by the ring-like end of--a'lever d, internally-projecting ribs 7 7 atopposite sides of the holder e engaging in correspondingly- `shaped grooves in opposite sides of the cylinder b, so as to prevent the latter rotating in its holder e. The lower end of the cylinder b projects a short distance from the holder e and is supported on the bent end of an ad` justable stop-pin 17. The cylinder is kept to The same characters of referenceiudicate 'the same partsin the severalfig'ures of the its bearing on the stop-pin 17 by a coiled spring 19, occupying the upper portion of the holder c, the said spring bearing at its lower end on the cylinder b and at its upper end against a screw-cap 1G, by which the upper end of the holder e is closed.

The solid lubricants a l) are so arranged and manipulated by the lubricating appliance that they are separated a short distance apart while the engaging hook f of the ordinary pile-wire-withdrawing mechanism is drawing lhe eyed end of the pile-wire past the said solid lubricants and are then brought together and made to bear on the pile-wire c, so

as thereby to very efficiently lubricate thesaid pile-wire. Vhen the pile-wire c is wholly withdrawn, the solid lubricants a b are again separated.

The lower end of the solid cylindrical lubricant c is secured in a short tubular socket or holderg, arranged axially in a tube or case 7L, which is capable both of a rising and falling motion and also a rotary motion in-a second or outer tube or case t, fixed by abracket 7c to the side of the loom.

Arranged at the upper end of the tube or case his a plurality of pulleys m, over which pass cords l, that are attached at their inner ends to and support the holder g Within the tube or case 7L. The outer ends of the cords l are attached to the annular weight or ring n, which surrounds the tube 7L and is adapted to move up and down between said tube h and the casing'i. Attached to the upper end of the tube 72 and passing through an opening in the casing/L' is a suitable bracket on which is adjustably mounted a stop o in the form of a bent arm, the upper end of which extends over the edge of the cylindrical lubricant c and limits the upward movement of said lubricant. It will be seen that as the cylindrical lubricant wears away it will be raised and held in contact with the stop o by the sinking of the annular weight n in the cas ing fil.

The lower end of the inner tube or case z is attached tothe head ofa vertical spindle p, which rests on a spring-pressed lever r, fulcrumed at s, the other end of the said lever having a stud t, which by the action ofthe spring u of the lever o' is made to bear on a quadrant-shaped cam fr, which turns with the lever w of the ordinary pile-wire-withdrawing mechanism of the loom. The cam u has two rises, (marked, respectively, 1 2.)

The lower end of the vertical spindle p has on it a ratchet-wheel y, and carried by a spring-slide .z-'on one side of the lever 'r is a spring-pressed pawl 3. \Vorking in conjunction with the said ratchet-wheel y] is a springstopi. l The slide is attached, by means of ai flexible but inelastic belt or band 5, to a fixed bracket G.

'lhe short arm of the lever (l, by which the upperlubricating-cylinder Z) is carried, is pivoted on a stationary bracket or support atiached to the machine-frame and is connected by a cord S to the lever r, so that when the lever a is turned on its axis in the direction proper for drawing the solid lubricante away from the pile-wire the motion of the said lever o' will effect, through the cord 8 and lever (Lthe simultaneous raising of the lubricant b. The tubular holder e of the said lubricatingcylinder b has on it a ratchet-toothed ring or collar 9, and on one side of the lever d is a slotted slide 10. The said slide 10 has on one end a spring tooth or pawl 11, by which on the motion of the slide 10 in the direction of the arrow in Figs. it and 6 the ring-1ike collar 9 and tubular holder c are partially rotated, as is hereinafter described. On the other side of the lever d is a spring-stop 12, (see the plan Fig. 6,) which engages with the teeth of the ratchet ring or collar 9 to prevent the back rotation of the said ring or collar 9 and tubular holder e. The slide 10 is operated by a supplementary vlever 13, the arms of which are slotted, the yslots in the said arms working (on the motion of the lever d) over pins 14E 15, projecting, respectively, from the said lever d and slide 10. By the engagement of the lever 13 with the pin 14 the said lever 13 is on the motion of the le- Ver d rocked on its pin or axis 20, and by the engagement of the said lever 13 with the pin 15 of the slide 10 the said slide 10 is made to perform a backward and forward motion Qn the rocking of the lever 13, and thereby to ef`"-`-` feet, through the spring-pawl 11 of the slide 10, a partial rotation of the ring` or collar 9 and the tubular holder c.

The action 0f the lubricating appliance is as follows: Vhen the lever wof the ordinary pile-wire-withdrawing mechanism of the Jacquard loom takes the fullline position represented in Fig. 1 for engaging its withdraw ing-hookf with the eye of the next. pile-wire to be withdrawn, the rise 1 ofthe cam c comes under the stud t of the lever fr and effects the tilting of the lever r, (against the action of its spring u,) and consequently the separation of the two solid lubricants a l), the tilting motion of the lever o' being transmitted to the lever (l, carrying the upper lubricant b, through the cord S. The motion ofthe lever d effects the partial rotation of the holder of the upperlubricant Z7, as is hereinbefore described. At the same time the downward motion of the spindlecarrying end of the lever r effects thepnlling of the slide aand pawl 3 to an extent sufcent forturning the ratchetwheel y through the space of about one or two teeth, in which position the said wheel is retained by theratchet-stop 4t. On the motion of the lever w in the direction of the arrow in Fig. 1 for withdrawing the pile-wire c the stud t descends the rise 1 of the cam c, and through the turning of the lever o' under the action vof its spring u the two solid lubricants a Z1 are brought together and are made to bear on the pile-wire c just as the eyed portion of the said wire c has passed the said solid lubricants. On the lever w completingits back IOO motion,as indicated in dotted lines, thesecond rise 2 of the camo comes'under the stud t and again effects the separation of the two lubricants ct b and also the partial rotation through a small angle of the said lubricants a. b. By the intermittent partial rotation of the solid cylindrical lubricants a b the grooving of the acting ends of'the same which would result from continually drawing the pile-wires across the said ends in the same line is prevented. Y

The automatic adjustment of the solid cylindrical lubricant a to compensate for wear or consumption of the lubricant is effected by the annular weight n.

Although I prefer to employ both .lubricants a and b, yet I wish it to be understood that the solid lubricant a only may be employed.

It will be understood by those conversant with Jacquard and like looms that as each ot' the pile-wires is in its turn brought opposite the lubricatingappliancehereinbefore described, all the said wires are successively and automatically lubricated on their withdrawal from the carpet.l 1

By lubricating the pile-wires with solid lubricants in the ways hereinbefore described not only is the soiling of the carpet with liquid oil prevented, but the slay and pile-wires are preserved clean and otherV minor advantages result therefrom. v

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-
